Anacharis help

i tryed to keep an anacharis but it died soon after i got it....... same symptoms as yours, i too am stumped
 
is it floating?? try floating it if it's not.

but it generally does better with good light.

remember many times when you get it . it comes from a pond or tank often with natural light.
it my die back a bit then restart.
